SERVICE MANUAL NUMBER 22
Cleaning
IMPORTANT: Never use a caustic cleaning solution, as it may attack aluminum. Also,
never use a wire brush which could damage impeller or mating surfaces.
1. BEFORE cleaning, inspect the disassembled parts for burning, abrasion, carbon
deposits, gas and oil leakage.
Always wear safety glasses when using compressed air to protect from hose
rupturing or flying debris.
When using compressed air to dry components, Do NOT spin turbine, or allow
turbine to spin, since no oil is being provided to the bearings and could result in
damage to the bearings.
2. Thoroughly clean all the parts with clean diesel fuel, using a soft brush. Dry with
compressed air.
